I've recieved the 66 Avanti II I won on E-Bay and have a question. Down here in Ga. and its been pretty hot as of late but there seems to be a whole lot of heat coming through the firewall and floorboards of this car. Has anyone tried any heat sheilding mat to help with this problem in their Avanti? If so what brand [Dynomat seems to be quite expensive]? Did it work? Tips? Thanks all,

Darryl C. Lewallen Clarkesville, Ga.

If you don't get a response here, try the AOAI message boards.

There are a lot of Avanti club members who have done a good many modifications to their cars.

To be honest .. I think that a LOT of that heat is coming from the
heater itself. It doesnt seem as though you can shut the darn thing
off! I get the same experience with my '63 Avanti. Heat heat heat.

It has AC located in the console if thats what your describing? The AC works and does make it bearable but thats all.

The dynamat does work. But check all of the grommets on the fire wall.heater hoses, throttle boot, sterring ,brake and clutch pedal. Rubber seal for the hood. it will let hot air pass to the fresh air opening and heat up the inside to.these are most of the places hot engine air will get in from.;)

The console cooling modification JDP was referring to is on the later cars, ducting air from the cowl opening behind the hood bringing air down to the underside of the console to help cool that area. It definitely should be added to the earlier cars without it.

Make sure the rubber strip at the back of the hood is still sealing. Otherwise, hot air from the engine will come out of the hood, into the cowl vent and into the car and the ducting.

Stude controls are not the best. Check to insure your heater valve is fully stopping hot water. Also insure the defroster vents haven't "perished" as the Brits say. Most are shot and need replacing.

Replace every piece of rubber on the firewall. An amazing volume of heat can come in via a "perished" accelerator boot.

Combine the advice below with Tom's (sbca96) heater advice and you can actually get the temp down to "no worse" than any other non A/C car. I insulated mine from top to bottom, plugged and sealed every opening in the firewall and put in a new heater valve and it has become "normal".

The hood to cowl seal, brake and throttle seals and heater valve top the list.

Hello Darryl
My 64 Avanti R2 is also very hot in summer. I live about 40
Miles east of Atlanta.My Avanti is black not a good color for
summer heat.I just installed a new headliner & put some foil
insulation above the headliner.I am going to put a light under
the hood & at night look in the car to see if any light comes
through the firewall.Mabe you like to join our north Ga SDC
chapter.

Not putting the exhaust wrap down. But Thermal coating the the exhaust system will do the most good. Cuts surface temp in half.:DMost likely about $12.00 a foot. Wont cause any problems of rust by traped moisture.:(
